Shield
Scarlet and white are the colors used for the Corps of Engineers. The red horizontal and vertical areas represent a beam supported by a post and allude to the constructional function of the Battalion. The cannon and bayonet refer to the initial organization of the Battalion, it being formed from existing companies, formerly elements of Artillery and Infantry units; and likewise signify its combat designation. The dual mission, engineering and combat, is further indicated by the dovetail, a construction principle, interlocking the two functions. The scimitar is for the Tunisian Campaign and the broken ax for Italy.
